SoScprpio, may be what matters here is that the medication hasn't helped to reduce your depression. If it is changed with another now, you may expect 2 - 6 weeks before it works. On your first post on the thread you related your depression to the winter. In 6 weeks from now it soon will become Marc, the time when winter-depressions usually disappear. May be it's not worth to try another medication? If you are not manic now, perhaps the best is to stay at Wellbutrin until you can have a proper screen by specialists. I wouldn't have used so much time thinking about if you are bipolar (manic) if I were you. I would have let the specialists set the diagnosis either it is unipolar or bipolar depression and then tried to be in an active transaction with the specialists (have good communication). Please remember that what your mother called manic doesn't have to be what is clinically manic.
In many cases the meds aren't expected to do the job with depression alone. Often a combination of therapy and medication are meant to be the «working force» that together will bring about a relief in symptoms. In therapy you are expected to cooperate, that is doing your part of the work as you sure know. Since you have to wait ca three month there isn't so much you can do now other then to try the best way you can to cooperate with yourself (not get stuck in thoughts about what it is rather then to try to live the best way you can with your symptoms).

I very much agree with Lefty the Salesman about that it can be wise to try to find a support group near you. If you cannot find anyone, an alternative could be to try to find one on-line if that is possible. Another option is to continue to "talk" here at psychcnetral.
